Cast of grey's anatomy - Grace lyrics

I'm on my knees Only memories Are left for me to hold Dont know how But Ill get by Slowly pull myself together Theres no escape So keep me safe This feels so unreal Nothing comes easily Fill this empty space Nothing is like it seems Turn my grief to grace I feel the cold Loneliness unfold Like from another world Come what may I won't fade away But I know I might change Nothing comes easily Fill this empty space Nothing is like it was Turn my grief to grace Nothing comes easily Where do I begin? Nothing can bring me peace Ive lost everything I just want to feel your embrace
